(Cl. 18S- 190) 39 Claims. 1 VThis invention pertains toV a brake'beam support for a railway car truci: and more particularly to a compensating type' thereof.

A particular and broad object of the invention is the provision oi an adjusting or compensating means so associated with a side frame and journal box that, irrespective of the vertical travel of a side frame relative to a journal box, a brake beam will be maintained in a deiinite and fixed position.

A feature of the invention is the provision of rigid means pivotally secured to a side frame so as to be carried4 vertically with the side frame and having spaced portions respectively and flexibly secured to a journal box and a brake beam support or guide.

An added feature o1" the invention is the Drovision of a vertically directed member positioned inwardly of a truck with vertically spaced means pivotallyV connecting the member toa side frame and being responsive toa vertical action-between a side frame and journal box.

The above objects and features, as Well. as numerous others, will become apparent from the succeeding description considered together with the accompanying drawings, wherein:

Referring now in detail to the drawings. wherein, throughout the several views, like reference characters indicate like parts, the-structure of Figures l through 6 illustrating one specieoi the invention will be considered initially. The railway car truck, indicated generally by the reference character l, comprises a pair of transversely spaced, longitudinally extending side frames, only a portion 2'ofcne of'which is' illustrated because it is commonly known that a rail- Corporation, f' Depew,

The railway' c'ar` truckVV with which' the present invention is particularly adaptable is a type thereof wherein 'the side frame is res'iliently supported and, accordingly,fthe ver-tical disposition of the side frame is"` most usually continually changing in runningT service and also during the loading and unloadlngf lthecar body. Asillustrative of the type of railway car truck hereinabove discussed, therefisf'shown a journal box E forming a housing', forbearingso'f any type (not shown)` and whichare operatively associated-with a` wheelandv axlelassembly l.

YBarrows etzal.l VIn'such a railway car truck, because yof the presence of the flexible or resilient support, and considered `together with the factV that the verticahdispositionof the axis ot the wheelandvaxleassembly is,` throughout all servicetruck= movements, :constant with respect toasuppOrtingraiI; the vertical relationship between theside .frameandwheel and axle assembly is subject ltoV variation.

Generally, .the means:` employed ttc impede the progress of.arailway car: or `retain a railway car in-agpredetermined positionpis acomponent of a railway car trucknommonly'called a brakebeam and designatedlin the severalfviews of thedrav ing `by--. thev referencercharacter Iii. The brake bearn-v extends horizontally or transversely of the truck` and has associa-ted with extremities thereoffbrake shoe/heads Il--which carryreplaceable brake shoesV Ha arrangedtoconta'ct the wheels of a ywheel and' axle assembly.

.For reasonswhichfareapparent to those skilled in the art-andeneedfnot .beherein enumerated, ari-ideal condition-iis. attained Vwhen the brake beam,v thoughsupportedfby apart ofthe railway truck, is i maintained..-I at` afl predetermined elevation: -so that-,.- irrespective .or f any 'vertical' `variationk between the side frameand'k wheel .and axle assembly, .the brake `'beamAv-willz at l all. times' travel plication or release action of the brakes. Toward the attainment of the above there is provided a brake beam carrier or support I2 desirably of cast form but, as will be apparent, may be made equally as well as a fabricated component. The instant species is primarily concerned with the type of brake beam having an extension I3 of elongated cross sectional conguration which projects outwardly of the truck from a related brake head in contrast to the type employing a pivotal or swing hanger interlocked with the brake head. Accordingly, the brake beam support has, at a lower extremity thereof, a guideway I4 formed by top and bottom walls I 5 and I6, respectively, spaced one above the other and both being joined near or at their wheel adjacent extremities by an end connecting wall Il. The guideway is further defined by a side wall i3 joining the previously mentioned walls so that the guideway opens inwardly of the truck both toward the longitudinal and transverse center lines thereof. Accordingly, the inside of the guideway is open for accommodation of the brake beam extension I3, and what might be termed the rear side of the guideway is open so that the brake beam may be introduced into the guideway through this latter mentioned opening. Carried by the top and bottom walls are bearing or wear plates I9 secured to the related walls by any desired means. As previously indicated, the extension I3 of the brake beam projects into the guideway and is retained in this position by the related walls and the wear plates associated with the top and bottom walls. From long and established practice, brake beams are most usually disposed below a horizontal plane bisecting the axis of the wheel and axle assembly, and are arranged so as to move along a path which, if extended, bisects the axis of the wheel and axle assembly so that the included angle between the extended path and horizontal plane above mentioned will approximate 12 degrees. Accordingly, the guideway is inclined or disposed upwardly and outwardly or longitudinally of the truck so that the brake beam will travel, during application and release of the brakes, along a path which, if projected, would intersect the axis of the wheel and axle assembly and present with a horizontal plane, an included angle approximating 12 degrees.

As previously implied, means has been incorporated in the truck to maintain the guideway in a xed position and, as exemplary of such a means, there is provided a bracket, depending means or stationary hanger formed by a plane web 2| integral with and extending downwardly of the truck from a tension member 22 of the side frame and intermediate the bolster opening 5 and journal box accommodating jaws. The plane web, disposed desirably along an outer edge of the tension member, has its free or lower end terminating in an apertured hub or bearing member 23, the axis of which is substantially horizontal and arranged at an angle to a vertical plane extending longitudinally of the side frame. In order to reinforce the bracket against stresses to which it will be subjected in service, an inner rib 2li is formed integrally with the web to eX- tend therefrom inwardly of the truck and have its respective ends merge with the tension member and hub. For a like reason, parallel outer ribs 25 outstand from the bracket web to extend between the tension member and bearing. Positioned toward an associated end of the side frame from the previously described bracket is an auxiliary bracket, depending means or stationary hanger 26 formed in part by a vertical wall 21 integral with a jaw 8 of the side frame between the journal box and bolster. This vertical wall is, in fact, a downward continuation of a part of the related jaw on the outer side of the side frame so as to not interfere with any of the truck main components. The vertical wall also terminates in a hub or bearing 28 which has an axis in substantial perfect alignment with the axis of the bearing 23. Because of the short effective length of the Vertical wall, it is believed only necessary to reinforce it against service stresses by a single stiffening rib 21a outstanding from the vertical wall as an integral part thereof and joining the related jaw and bearing 28. Extending through and connecting the aligned bearings is a pivotal bar, pin or shafts 29 which may or may not be arranged to rotate about its axis relative to the supporting bearings. The shaft has extremities 3G projecting beyond the bearings to thereby present cylindrical, outstanding horizontal axles.

Carried by the shaft axles is an integral, firm, rigid means or crank 3I desirably substantially Ushaped in plan and comprising an intermediate shank or bar 32 which extends horizontally for at least the distance over the spaced bearing and is of semi-circular or arcuate configuration in cross section with the inside radius thereof slightly greater than the outside radius of the bearing. By reason of this shank configuration the crank is easily or readily associated or assembled with the hangers and is free to rotate within certain limits about the axis of the shaft axles. Associated with each end of the shank is an annulus or washer type end wall 33 forming in effect a barrier or end closing of the shank. The end walls telescope or overlie the bearings to be disposed in the close proximity thereto and are provided with suitable apertures which accommodate rather neatly the shaft axles so that while the rigid means or crank is arranged to rotate about the axis of the shaft it is also prevented from shifting in a direction axially of the shaft. Cotters or any removable means 3d are associated with the free ends of the shaft axles to prevent an unwarranted or accidental displacement of the shaft.

Extending inwardly of the truck from the annul-us adjacent the jaw hanger is a stili?, iirm arm 35 desirably of U or channel shape in vertical cross section and projecting toward the area beneath the related journal box Where it terminates in an angularly directed pin or journal 35. The axis of the journal is also disposed horizontally and at an angle to the vertical longitudinal plane of the side frame hereinabove referred to so that the axis of the journal is parallel to or substantially so but spaced from the axis of the rotary bar or shaft for reasons which will be hereinafter made apparent. Because the side frame moves vertically relative to the Substantially stationary journal box and also because of the slight tolerances between juxtapositioned guiding surfaces of the journal box and side frame which allow a slight transverse movement between the journal box and side frame, it is believed at the present writing that the juncture of the arm and journal box should be made exible. While it might be quite feasible to permit the journal o-f the arm to ride in a groove beneath the journal box it is, however, preferred that the journal extend through a round or cylindrical bushing 3l which is embedded in a block 38 of relatively resilient material such as rubber, rubber compound or the like. The resilient block has upper and lower wearing or -rubbingiplates 439 securely bonded thereto. ,So a-s to maintain the block. and hence the arm journal ina somewhat fixed and predetermined position, a .strap or .1J-.shaped bracket l0 is formed preferably integralwith `the bottom of the journal box, and thus the block cmd wearing plates are arranged inrfther vertical space between the journal box bottomand strap. 'The free Lend vof the journal istprovided with a transverse slot into which `is threaded a .clip 41 retaining a washer 42 in position against the block thereby lockinglthe block to the arm journal. Because of therelative compound action between the journal 'boxandasideffrarne,A as `well as -the fact that the positionof shaftis fixed with respect to the-side "frame, the strap `is somewhat elongated in order thatr'theblock and encased journal may, in servica'movein a direction substantially transversely .ottnetruck It maybe well to here `mention thatlypreferablyithc 'vertical center of the block .coincides-normallywith the vertical center of the journalibox as illustrated by the intersecting diagrammatic lines in Figure 2. By this alignment .of vertical 'centers it is believed that a true and aecurate'verticalfmovement between the journal 'boxandv-side'frame will `be reflected in the integral or rigdmeans or crank. It will, of course, be appreciated that the vertical centers above mentioned neednot vbe in alignment and `no such limitation .is totbe read into this description-as it. is not implied Yor intended because a reflection of the journal box-side frame movement may be equallyeective by the arm or arm journal being associated with any part of the journal box.

Extending inwardly ofthe truck Jfrom-the other annulus is aiirm, rigidarm 43 which'may be classied as `the-.guide arm-- as opposed tothe previously discussed arm,l the flatter of which also for thesake of convenience and .identication, may be termed as :the journal box arm. The guide arm, also of'channel cross secton,ipro jects beneath the side frame through the plane thereof to terminate in-a 4boss or embossment '44 having an aperture in laxial 'alignment-with the journal box armjournal. Depending from the bottom wall of the brake beam-support is a pair oi spaced lugs or ears larrangedzin straddling or overlapping relation with'fthe 'guide arm boss and correspondingly .apertured toi accormnodate a hinge `pin Mi pivotally connecting the .guide arm and brake beam support. VThe brakeA beam support is thus carriedinailxed,` ydefinite or predetermined position and because the effective lengths of the journal boxarm't and guide arm t3 are equal, a verticalrmovement`A of the side frame relative to the journal -box will vresult Ain the pivotal bar 29' being carried vertically through a corresponding distance. 'Aspreviously stated, the journal box or the wheel and axle" assembly remains at a fixed elevation and-'when the side frame moves vertically1 Athe rigid li'iealis or crank 3l Will DVO about the pivotal bar-butthe brake beam support l2 wilt-like the journal box, remain at a xed elevation lao-permit the brake beam to travel along its xecl. predetermined. pathtoward or away from the axis of the-wheel and axle assembly.

Because of the pivotal' connection between the guide arm and brake beam-support it is believed advisable to steady the brake beam `support with an additionalconnection and, accordingly, a co1- umn il of the side fra'melis providedwith an inwardly directed bearing while spaced hori- Zontally therefromis'an outwardly-directed bearing 49 outstanding from thesiderlframe at the juncture of the tension member Vand compression member 50. The axes of these .upper .or two latter mentioned bearings are'in horizontal alignment and desirably inyertical alignment and parallel to but spaced above the raxis of the pivotal bar so as to beangular to the vertical longitudinal plane of the side frame. The :space between the upper bearings Vis apart of a side opening 5l in the side frame which is bounded by the compression. member, the tension 4member and the column. Threaded through the upper bearings and bridging the Aspace therebetween `is a pivot rod 52 locked in operable positionbythe presence of Cotter pins or keys 53 associated with the respective ends of the pivot rod outwardly of the bearings. .Sleeved over thepivot vrod :between the upper bearings is a link 54 comprising spaced sockets 55 joined by an intermediate spacer 56, the latter of which is also? of circular cross section or of substantiallysemimylindrical formation to be spaced 'iromthe pivot rod. The sockets .aand intermediate spacer-have, extending therefrom, inwardly of the truck through the side frame side opening, a leg 51 with peripheral, angularly disposed, side Stiiening anges 53a 'to terminate in an apertured `cylindrical extremity 58. The effective length of the link is equal'to the effective length of the guide arm and, ac cordingly, the axis of the cylindrical extremity is parallel to the axis of the -piny fit'and desirably spaced directly thereabove.

The top wall i 5 of the guideway has, upstanding vertically therefrom, a pair-ofspaced standards, stanchicns Vor postsv 5S which extendfupwardly from the top wall to embrace the'cylindrical link extremity therebetween. `Aperturas are provided in the posts attheir .upperflimits with the apertures being disposedin axial alignment with the cylindrical extremity of the link to accommodate a pivotpin Sil removably securing the link to the guide posts. Accordingly, When the side frame moves vertically relativeto a journal box, the pivot bar 52 and shaft 29 will be carried through the same distance and, because of the particular equal lengths Vand disposition of the link 54 and guide arm 43,.the guide means I2 will .be heldin aA predetermined, xed or illustrated position. If desired, a gusset 6! may be provided at the juncture 'of one of the posts and guideway top wall and a connecting plate 52A may be formedntegrally with the posllzs immediately below their connection'tothe 1in Referring now in detail Vto the second specie of the inventionl illustrated in Figures 7, 8 and 9, there is disclosed a portion of `a railway car truck la including a pair of side frames, only a portion 2a of one being shown. Connecting the side frames intermediate their ends isa bolster elenient 3a having an end portion 'ea lnterlocked with a side frame to form a kconnection between the two transversely spaced side frames.r In like manner, each side frame under immediate'consideration is supported at each end thereofby a journal box 5a with resilient means V(not shown) disposed between the side frame and journal box. The present truck has associated therewith a brake beam 9a having an extension Ia and adapted to move toward and away from a wheel of a wheel and axle assembly la. Carryingfthe brake beam is a brake beam support l2a`positioned inwardly of the truckV and comprisingl a bottom wall Ita underlying and functioning as a bearing for thebrake beam extremity. The

bottom wall is inclined so that the center line of a guideway |461., partially defined by the bottom wall, intersects the axis of the wheel and axle assembly so that the included angle between the extended -center line and a horizontal plane bisecting the axis of the wheel and axle assembly will, as in the previous case, approximate 12 degrees. Closing the outer side of the guideway is a vertical side wall lSa upstanding vertically from the outer edge of the bottom wall and merging into a somewhat narrow top wall Ia which is parallel with the bottom wall but spaced a predetermined distance above the latter. The narrow top wall, side wall and bottom wall are all joined integrally adjacent a common extremity by an end wall lla which closes one end of the guideway. In the instant structure, for reasons which will be later explained, the narrow top wall extends across only a portion of the upper limits of the guideway where it merges into an upstanding barrier or vertical web 53 which extends, along its length, for substantially the full length of the narrow top wall. Projecting inwardly of the truck from the upper extremity of the barrier is an overhanging lip fifi which may, if desired, be made as illustrated and thus, coextensive with the barrier. Disposed within the offset formed by the vertical web and lip is a leg 65 of a shelf 65 with the leg being removably attached to the vertical web through the medium of any means such as the illustrated rivets 6l. Another leg 88 of the shelf is angularly disposed to the iirst named leg and forms, in effect, a continuation of the narrow top wall to be substantially coextensive therewith and complete the top wall so that the upper limits of the guideway are thus defined to guide or direct a brake beam toward or away from a wheel. Wear compensating means is associated with the guideway as exeinplied by the wear or bearing plate lSa which is of sinuous formation in cross section and comprises a base plate E9 having a clip-like edge l curling about the free edge of the lower wall. The other edge of the base plate merges into a vertical ange 'il which lies against the side wall and turns into a reentrant flange l2. Upstanding from the reentrant flange is a nib or short finger or n 13 extending into an accommodating relief and bound between the narrow top wall and shelf to retain the bearing or wear means or plate in operable position.

Depending from and integral with the side frame are brackets, depending means or hanger elements 29a and 25a spaced a predetermined distance apart and carrying at or adjacent their lower extremities hubs or bearings 23a and 28a respectively. The hubs, which have their axes in alignment and disposed at an angle to a vertical, longitudinal plane of the side frame, accommodate a pivotal bar or shaft 29a with the latter carrying, through its cylindrical extremities Sa, an integral, rigid means or crank Sla. The present crank is identical with the previously mentioned crank 3l and, accordingly, has a journal box arm a underlying, interlocked with and actuated by a journal box Sa through the medium of a flexible connection Sa and a journal box clip a. In like manner, a guide arm Sa extends from the other end of the rigid means shank 32a to be interlocked through the medium of a pin a to spaced lugs or ears @5a which depend from the guideway bottom wall. As in the previously discussed structure, the instant specie is provided with bearings 48a and 49a to carry an angularly disposed pivot rod 52a while a link 54a connects the pivot rod and upper extremities of stanchions or posts 59a upstanding vertically from the brake beam support vertical web.

A further distinction between the two illustrated species of the present invention resides in the alteration in design of the brake beam support. In this regard it is deemed advisable to here state that in lieu of guiding the brake beam extremities along a fixed path, through the medium of the guideway, it may be desired to suspend the beam from a swing hanger illustrated diagrammatically in all of the figures showing the second specie and designated by the reference character lll. For reasons that are obvious to those skilled in the art, an operator may require either a guideway or a swing hanger for the support of a brake beam and, with this thought in mind, the brake beam support includes a vertical plate-like rib l5 formed integrally with one or the bolster adjacent post of the pair of posts 59a. The rib extends upwardly from a portion of the lip 64 to terminate horizontally away from the posts in a normally disposed end flange 16, the latter of which is carried down over and formed integrally with the barrier 53, narrow top wall and sidewall. At or near the upper limits of the end flange a jaw 'il is formed to open away from the bolster and be spaced inwardly of the truck from the plate-like rib. The jaw, desirably in longitudinal alignment with the wheel of the wheel and axle assembly, comprises transverse extensions i8 of an upper portion of the end flange and upwardly vertically spaced fingers or ledges i9 which, near their free ends, are apertured to accommodate any type of removable retaining means such as a pin (not shown). The swing hanger, if required in lieu of the guideway, is associated with the jaw to be interlocked therewith and functions as an optional movable support for the brake beam. When the swing hanger is employed, the shelf 66 as well as the bearing plate lila is omitted from the structure, because the former interferes with the successful operation of the swing hanger and the latter is not required. It is to be noted, however, that irrespective of the medium employed for supporting the brake beam, namely the guideway or swing hanger, the remaining components will function as hereinabove described and thus act as a compensating means for maintaining the brake beam in a substantially fixed, elevated position relative to an associated wheel of a wheel and axle assembly.

From the above it will be noted that various changes and alterations may be made to the illustrated and described constructions without departing from within the spirit of the invention and scope of the appended claims.
